LEAD OR CRAYON HOLDER.

SPECIFICATION forming part of Letters Patent No'. 272,931, datedFebruary 27', 1883.

Application filed November 14, 1882.

T all whom it may concern Be it known that I, GEORGE B. ADAMS, a

citizen of the United States, residing in Newark, Essex county, NewJersey, have invented certain new and useful Improvements in Lead orCrayon Holders, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

This invention consists in a particular construction of a lead holder orcase containing a movable lead-carrier and a sliding cover or sleevefitted to the exterior of the case.

It also consists in so constructing the slid- .I 5 ing sleeve that itoperates, independently of its clamping function, as a cover or guardfor the point of the lead when the latter is not in use.

The invention will be understood by refer- 2o ence to the annexeddrawings, in which three equivalent constructions are shown.

Figure l is a longitudinal central section of a holder constructed withmy improvement, the section being taken on line a a in Fig. 4, 2 and thelead and lead-carrier not being cut by the section plane. Fig. 2 is asimilar view of a holder with a modified form of catch, the sectionbeing taken at the central line, as at c c in Fig. 5. Fig. 3 is anexternal view of the 0 construction shown in Fig. 2, the view being inthe direction of the plane 0 c in Fig. 5. Fig. 4 is a section on linearat in Fig. 1. Fig. 5 is a section on line y y in Fig. 2. Fig. 6 is asection on line 2 z in Fig. 2, and Fig. 7 is a transverse section of acase lined with a metallic tube, as in Fig. 10. Fig. 8 is a detached topview of the lead-carrier shown in Fig. 1. Fig. 9 is a similar view ofthe lead and lead-carrier shown in Figs. 2 and 3; and Fig. 10 is a sec-I 40 tion of the lined case shown in Fig. 7, taken on line to w in thelatter figure.

A is the case, formed with a bore, B, to admit the lead d and carrier O.

D is a sleeve, formed of a tube applied to the exterior of the case,andmovable lengthwise thereon. It can also be removed entirely orpartially from the case to obtain access to the clamp of thelead-carrier when the latter needs adjusting to compensate for the wearof the lead.

(No model.)

The carrier 0 consists of a-tubular socket for grasping one end of thelead (1, a clamp, 0, upon. which the sleeve D can act, by pressure,, anda catch, t, adapted toengage the case when pressed against the same bythe action of the sleeve upon the clamp.

To obtain a connection between the carrier inside the case A and thesleeve outside of the same, the sleeve is formed with a longitudinalslot, f, and the clamp c is shaped as a thin lug attached to thelead-carrier and projected through the slot in contact with the in sideof the sleeve D. To grasp the lead sccurely, the nozzle of the tubularcarrier is preferably split at several points, as at l in Fig. 6 8, andthe bore of the tube is contracted in the rear of the nozzle to limitthe entrance of the lead to merely grip or hold thereon. To secure thecarrier at any desired point in the case, and thus obtain. a properprojection of the lead beyond the point for use, the carrier or theclamping-lug c is provided with a projecting or roughened part, '5,adapted to press into or grasp upon the caseA when actuated by thesleeve D. Such a projection, i, V

is shown in Fig". l at the rear lower corner of the carrier, theclamping-piece e being attached to the rear upper corner of the same, sothat the pressure of the sleeve operates to push the projection i intothe wood fortnin g the bore B. To render the pressure of the sleeveelastic and to compensate for wear in all parts en.- gaged in thussecuring the carrier, the latter is shown split in two at its rear end,as at min Figs. 1 and 2, the split extending nearly to the contractedpart of the tube, and the divided parts thus being made capable ofyielding under the pressure of the sleeve. \Vhen the sleeve embraces thecase and clamp c, as shown in Figs. 1 and 4, the upper and lower'partsof 0 the carrier, where split, are pressed toward one another and anelastic pressure exerted upon the bottom of the bore B by the carrier.Except when perfectly smooth, such pressure and its consequent frictionmight serve to hold the carrier in the desired position; but theprovision of the catch 1, or any equivalent roughening of the bearingparts pressed together by the sleeve, obviates all risk of the carriersslipping when it wears smooth. hen the sleeve IOC Dis entirely slid offthe case A, or moved longitudinally far enough to uncover theclampingpiece a, the pressure of the carrier against the tube isobviously removed, and it may be shifted forward in the bore B toproject the lead or backward to admit a new lead. WVhen thus unclampedthe carrier may be moved by grasping the projecting end of the lead atthe nozzle of the pencil, or by pushing the piece 6 to or fro in theslotf. The latter is shown in Figs. 1 and 2 as extended to neither endof the case A, and the carrier in such case can only be inserted bysplitting the case at the front end of the slot and springing it open toadmit the piece 6. If preferred, the slot may be extended all the way tothe front end of the case A, as shown in Fig. 3, and the sleeveconstructed to cover it completely, as shown in Fig. 1.

v The catch 6 is shown in another form in Figs. 2, 5, and 9, the piecebeing constructed with a flat plate atits outer end, adapted to bearupon the case A along the sides of the slotf, where the casing is shownin Figs. 1 and as slightly flattened, or reduced at b to admit suchplate inside the sleeve D. The rear corner of the plate is bent slightlytoward the case, so as to stick or press into it, as at i in Fig. 2,when the sleeve is slipped over it, thus securing the carrier fromslipping when pressure is applied to the lead, and the split at at therear of the carrier then operates merely to raise the catch 71 from theflattened surface of the case at b.

Although in practice I have made the case A of wood, it may be made ofany suitable material, or of wood lined with a metallic tube, slotted inagreement with the ease atf, as shown in the section in Fig. 7. In thelatter case the bottom ofthe metalliclining may be indented orperforated, as shown at j in Fig. 10, to engage the catch 2', formed onthe bottom of the carrier, as shown in Fig. 1, thus entirely obviatingthe risk of any slipping, the catch being readily slid over suchdepressionsj to adjust the carrier, when the sleeve is removed fromcontact with the clamp 0. Other means of catching the carrier in thebore of the case A may be devised to co-operate with the sleeve D to thesame effect as the catchesi shown in Figsl and 2, asawedge pressedbetween the split parts at the rear end of the carrier by the depressionof the piece 0. In such construction the split m would be arranged tocoincide with the slot f, and the piece 6 would be attached to thecarrier at the contracted part, and furnished with a wedge insertedbetween the divided parts. Such wedge would press the sides of the splitcarrier against the walls of the bore B, and thus clamp it in position.

The sleeveD is shown in Fig.1 formed with a nozzle adapted to cover'andinclose the entire front end of the case A, including the lead d, thecase being thereby adapted to protect the point of the lead when not inuse. The

nozzle of such sleeve is perforated opposite the lead, so that thelatter may protrude through it when the sleeve is pushed up, and thenozzle of the sleeve then comes in contact with the front end of thecase A, and the whole sleeve is held in such position by the frictioninduced by the resistance of the clamp 'e. The spring formed of thesplit end of the carrier is thus operative to hold the sleeve inposition, as well as to compensate for wear or irregular fitting of thecarrier in the bore B. and to cause an elastic pressure of the catchz'against the sleeve or bearing-surface in the bore. The sleeve may alsoserve as a guard for the exposed point of the lead without being shapedto fit the point of the lead or case, and is thus shown in Figs. 2 and3. In such case the sleeve consists merely of a parallel tube, and ismade about half an inch shorter than the case, so that the latter willproject that amount from either one end of the sleeve or the other, asthe user may desire, the sleeve being held in the hand, and theprojecting end of the lead or case being pressed against some solidobject to protrude the opposite end when required. The sleeve,constructed as shown in Fig. 1, is operated in a similar manner, thelead in either case being supported against such endpressure by theoperation of the clamp e and catch t.

From the above description of the sleeve it will be seen that itexercises a double function-first, in its combination with the clamp cand yielding catch t, and, second,in its combination with the case A andlead d, projecting from the nozzle of the case for guarding the latterwhen not in use. It exercises the first function by pressing the clamp einward and the latter one by sliding longitudinally upon the case A; andas I have shown more than one form for the catch 1', it is obvious thatothers might be devised, and that the sleeve may be properly regarded ascapable of performing this double function with other catches.

With the constructions thus described it is plain that the lead may befed forward as it wears by removing the sleeve from its contact with thepiece 0, and that a new lead can be readily inserted in the holder bysliding the carrier to the front end of the case.

I am aware that certain of the elements I have employed in my inventionhave been used before in other combinations-as theleadcarrier-and thecase A formed with slots of various kinds, and I do not therefore claimeither of them as my invention; nor do I consider a sliding guard asnew, except in the combination I have herein described and claimed, thesame having been combined with other ele ments, as in United StatesPatent No. 188,721, of March 20, 1877. The sleeve as used in myinvention differs, however, from said Patent No. 188,721 in exercising adouble function, as set forth above.

Having thus fully set forth my invention, any novel subject-matter Ihave described and not claimed or attempted to claim herein I haveclaimed in otherbending applications or have reserved to claim in futureapplications.

I therefore claim the same as follows:

1. The combination of the case A, having bore B and slot f, thelead-carrier 0, provided with clamp c, and the sleeve D,longitudinallymovable upon the case over the clamp e, and operated to hold the carrierin the case by pressure upon the clamp, substantially as herein setforth.

2. The combination, with the case A and the lead-carrier having clamp e,constructed and operated as described, of the sleeve D, constructed andoperated as described, to perform the double function of clamping theleadcarrier by pressure upon the clampcand guarding the lead-point bysliding longitudinally, substantially as shown and described.

In testimony whereof I have hereunto set my 20 hahd inthe presence oftwo subscribing'wit-
